MochetVelo Posted January 6, 2014 Share Posted January 6, 2014 The December Hupp Club newsletter offers a new "beefed-up" crankshaft at $350. Is that an item a Hupp owner should purchase as a spare? That is to say, do crankshafts tend to break?Phil Link to comment Share on other sites More sharing options...
trimacar Posted January 6, 2014 Share Posted January 6, 2014 I've heard of our Model 20's losing crankshafts when you brake too hard without pushing in clutch, thus that heavy flywheel on the front of the crankshaft torques and breaks...I think it's a good part to have on shelf, thinking on it myself...

Harold Sharon's advice was not to touch a cast crankshaft - I'll consider a bit further -Karl Link to comment Share on other sites More sharing options...
MochetVelo Posted January 8, 2014 Author Share Posted January 8, 2014 There are various repro Model T crankshafts that are cast, forged and machined from billet. The high-performance guys prefer the forged shafts, but a correctly-cast shaft should be fine for a low-power car like the Hupmobile Model 20. Here is a good article on the subject. The big question is the quality of this new Hupp shaft. Phil Link to comment Share on other sites More sharing options...
Max BURKE Posted January 9, 2014 Share Posted January 9, 2014 G,day to all. Edgar had a batch, I think four cast at a foundry here. They were cast in the iron that they cast the Ford falcon shafts in. Edgar tried to have the bearing journals cast larger but it was not practical. I think that he had the shafts Nitrided after they were ground. Anyway the whole process took far too long, may have been done piecework to keep Edgars cost down. Edgar always blamed the brakes for breaking the crank but as I have never seen or driven a Hup 20 that would lock the wheels on a Bitumen road @ 30 MPH I believe the cause is more probably misalignment of the main bearings. Few are line bored , individual bearings being bored in a lathe and hope alignment is Ok. but, what happens when the centre bearing bolts are pulled up to 40 plus ft lbs. How many times have the centre bearing halves been reversed and the rear main, the clutch hub, put on the wrong key to take up the slack in the drive keys. Imagine the shaft trying to align itself at every revolution. Hup dealers tried to convince the maker to improve the stoppers but it took until the very last production before they came out with full width cams and brake shoes, and even then the shoes were maliable iron and were far too heavy. My brother in law, who had a Hup 20 in the 20,s, always said," Hup 20, two speed, slow and slower, and both too fast for the brakes" Huppy new year.

I just have to work out the time difference between New Zealand and him so I don't ring him in the middle of the night ! -Karl Link to comment Share on other sites More sharing options...
MochetVelo Posted January 9, 2014 Author Share Posted January 9, 2014 Maybe you can post details about the crankshaft after you call Mr. Greene, Karl. I'm curious about how he went about this project, who made the pattern, alloy used, etc.Phil Link to comment Share on other sites More sharing options...
1910Hupp Posted January 12, 2014 Share Posted January 12, 2014 Phil I've spoken to one of my friends who is an engine reconditioner and his advice is not to purchase a cast crank . Therefore I don't think I will go with it . Given this I will skip the expense of a 1/2 the world away international call to Mr Greene-Karl Link to comment Share on other sites More sharing options...
MochetVelo Posted January 12, 2014 Author Share Posted January 12, 2014 But where can you get a forged crankshaft for the Hupp?Phil Link to comment Share on other sites More sharing options...
1910Hupp Posted January 12, 2014 Share Posted January 12, 2014 But where can you get a forged crankshaft for the Hupp?PhilYou can't get one (as far as I know) but you can carve one out of a forged billet -which almost certainly will be stronger than a cast crank. Cost is going to be more than $350 but even at this price the cast crank is going to need machining before use which will add to its final cost.
